The Big 12 features the nation's only 3-0 power conference team in No. 14 Iowa State. But does that make the Cyclones the No. 1 team this week in unveiling the new power rankings? ISU indeed shakes up last week's rankings, which features other big movers especially two teams making a jump five spots.

1. Iowa State (+1)

Iowa State Cyclones' quarterback Rocco Becht (3) and running back Carson Hansen (26) celebrate after winning 16-13 over Iowa in the Cy-Hawk football at Jack Trice Stadium on Sept. 6, 2025, in Ames, Iowa

The Cyclones now claim the top by pulling off the gritty 16-13 win over rival Iowa. Which also saw Matt Campbell and the Cyclones hit a feat not seen in a decade.

2. Texas Tech (+1)

Patrick Mahomes must be proud of his alma mater. The Red Raiders have scored 67 and 62 points to start the season.

3. BYU (+2)

The Cougars turned to defense by picking off Ben Gulbranson twice. Which offset a rather dismal offensive performance versus Stanford.

4. Baylor (+4)

The Bears enter the top five party here after knocking off No. 17 SMU. Outscoring the Mustangs with 24 unanswered points.

5. Arizona State (-4)

Arizona State Sun Devils quarterback Sam Leavitt (10) scrambles in the backfield as Mississippi State Bulldogs defensive lineman Will Whitson (43) and linebacker Malick Sylla (8) pursue during the second quarter at Davis Wade Stadium at Scott Field.

The reigning conference champs take the biggest tumble, but caps off the top five. Still, Mississippi State ignited through a 58-yard touchdown to pull the upset of the College Football Playoff team.

6. TCU (-)

TCU earned extensive rest after embarrassing North Carolina and Bill Belichick. The Horned Frogs get Abilene Christian before the huge Dallas-Fort Worth battle with SMU.

7. Utah (-)

Saturday was smooth sailing against Football Championship Subdivision (FCS) challenger Cal Poly (Utah 63-9). They face old Mountain West Conference rival Wyoming Saturday.

8. Kansas (-4)

The Jayhawks take a four-spot fall in losing the Border Game with Missouri. Kansas surrendered only a single touchdown in both wins before the Tigers entered the picture.

9. Arizona (+5)

Brent Brennan sparks one of the biggest jumps here and breaks into the top 10 with ‘Zona. Wildcats have averaged 44 points per game offensively post Tetairoa McMillan.

10. UCF (+5)

Is it too early to say this is shades of 2017 for the Knights? Scott Frost has UCF unbeaten again — demoralizing North Carolina A&T 68-7. They now get Bill Belichick and North Carolina in Orlando.

11. Houston (-)

The Cougars handled “H-Town” rival Rice 35-9 on Saturday. Friday promises huge early conference implications — as this opponent strolls through UH.

12. Colorado (-)

The Buffaloes and Deion Sanders want this game to become a college football recruiting showcase for one of their go-to areas on the trail. Looks like Ryan Staub will earn more snaps — even with Sanders denying its official.

13. Kansas State (-4)

KSU is earning the title of most schizophrenic team in the Big 12. The 1-2 Wildcats got upset by Army which came with a $1.175 million paycheck.

14. West Virginia (-4)

Ohio University pulled the big stunner Saturday over the Mountaineers. Head coach Rich Rodriguez now must get reacclimated with the Backyard Brawl against Pittsburgh this coming weekend.

15. Cincinnati (+1)

Cincinnati briefly got threatened by Bowling Green after racing to the 21-3 halftime lead. But pulled off the 34-20 win.

16. Oklahoma State (-3)

Mike Gundy sparked the hype for Oregon-Oklahoma State with his money dig at Dan Lanning. The Ducks and quarterback Dante Moore took it personal, though, in trouncing the Cowboys 69-3. Gundy and the Cowboys drop all the way down three spots to the bottom of the rankings now.
